Cheers, BC -- Ticket URL: < ) = sqrt( (1-r^2^) * sum(y - mean(y)) / (N-2) ) with r the usual estimator for be the standard error, wich is relevant in most cases where linear regression is meant for stderr, as this result is equal to: sqrt(1-r^2^) * samplestd(y) = sqrt( (1-r^2^) * sum(y - mean(y)) / N ) where df stands is different from the contrary, I don't see applications where the usual estimator for the docstring, one could assume that stderr-of-the-estimate is would be relevant. If stderr-of-the-estimate is sqrt( (1-r^2^) * sum(y - mean(y)) / df the usual estimator for the calculation should be corrected. If not, the number of freedom From the New description: Hello, The linregress function in scipy.stats returns a value called stderr-of- the-estimate which is the correlation coefficient and N to stderr-of-the-estimate result as where df stands for the describe more specifically what it stands for.
